Fate of weathered multi-walled carbon nanotubes in an aquatic sediment system.

The widespread application of carbon nanotubes (CNT) in various consumer products leads to their inevitable release into aquatic systems. But only little is known about their distribution among aquatic compartments. In this study, we investigated the partitioning of radiolabeled, weathered multi-walled CNT (C-wMWCNT) in an aquatic sediment system over a period of 180 days (d).
